Angelina is known for being focused on her ever growing brood of six kids, and it turns out she bonded with her Salt co-star Liev Schreiber because of it!

Salt stars Angelina Jolie and Liev Schreiber are devoted parents when they aren’t playing kick-ass characters on the silver screen. We got a chance to speak with Liev at the LA premiere of his film Salt, July 19, and he reveals that he and his co-star Angelina got along famously because of one thing … they have kids!

“For me it was mostly about being a dad and her being a mom,” says Liev. “That’s how we really bonded. That was the fun part because I think we’re both at that place with our kids where they’re really amazing.”

Liev, 42, is married to Australian beauty Naomi Watts, and they have two children together, Alexander, 3, and Samuel, 1. He might not have quite as many little one’s as Brad Pitt and Angelina’s growing clan of six, but Liev tells HollywoodLife.com their children are similar ages.

“Being around 3 year olds, language starts to come out of them and its a very exciting period in someone’s life,” he says. “Both having children and being parents, it was fun to kind of bond over that while we were shooting.”
